Wave shoaling is the process when surface waves move towards shallow water, such as a beach, they slow down, their wave height increases and the distance between waves decreases. This behavior is called shoaling, and the waves are said to shoal.n a nautical sense, a bar is a shoal, similar to a reef: a shallow formation of (usually) sand that is a navigation or grounding hazard, with a depth of water of 6 fathoms (11 metres) or less. It therefore applies to a silt accumulation that shallows the entrance to or course of a river, or creek.
Phosphorus (P) Phosphorus (P), phosphorusnonmetallic chemical element of the nitrogen family (Group 15 [Va] of the periodic table) that at room temperature is a colourless, semitransparent, soft, waxy solid that glows in the dark.
Phosphorus atoms have 15 electrons and 15 protons with 5 valence electrons in the outer shell. Characteristics and Properties. Phosphorus is a highly reactive element and, as a result, is never found on Earth as a free element.Elemental phosphorus comes in various allotropes (different crystal structures) including white, red, violet, and black phosphorus. The two major forms of phosphorus are white and red.hosphorus atoms have 15 electrons and 15 protons with 5 valence electrons in the outer shell. Characteristics and Properties.
